00:00:00.000 --> 00:00:04.340
Now, there is a problem with this mesh already.

2
00:00:04.341 --> 00:00:07.640
And it's not just this problem, which I am going to go in and fix.

3
00:00:08.180 --> 00:00:12.120
It is that actually this isn't manifold.

4
00:00:12.460 --> 00:00:15.340
This isn't watertight.

5
00:00:15.920 --> 00:00:20.700
It looks like it, visually, that this letter here is watertight.

6
00:00:21.080 --> 00:00:26.297
But if I pick a vertex and I move it around, you see it's

7
00:00:26.298 --> 00:00:31.080
actually not fully joined with each other, which is not good.

8
00:00:31.440 --> 00:00:37.500
So what I need to do is I have to do select all, press M, merge by distance.

9
00:00:38.640 --> 00:00:43.060
And the default, here's the margin of error for the merge distance.

10
00:00:43.440 --> 00:00:45.740
This is good enough for what we need it right now.

11
00:00:45.900 --> 00:00:49.360
And it has merged 2,000-something vertices.

12
00:00:49.680 --> 00:00:51.240
So it did its job.

13
00:00:51.420 --> 00:00:55.660
So now if I go to this and I move it around, yeah, it's all solid.

14
00:00:56.260 --> 00:01:00.300
Now, everything is watertight and good to go, except this.

15
00:01:00.560 --> 00:01:01.560
This is a problem.

16
00:01:02.360 --> 00:01:05.131
So what we're going to do is we are going to...

17
00:01:05.132 --> 00:01:07.780
and I can, by the way, I can isolate this also.

18
00:01:08.080 --> 00:01:10.160
It's maybe a little bit nicer to work with right now.

19
00:01:10.780 --> 00:01:13.800
Go into edit mode and I'm going to use the knife tool.

20
00:01:13.920 --> 00:01:17.900
So that's K and I, you know, there's a couple of ways you could do this.

21
00:01:17.901 --> 00:01:21.780
This is just the way I think is more elegant, visually, for me at least,

22
00:01:22.460 --> 00:01:25.980
is I'm going to kind of cut this part of the A.

23
00:01:26.620 --> 00:01:32.301
So I think it's more elegant than to awkwardly cut this section away from the L.

24
00:01:32.880 --> 00:01:33.460
Yeah, it's fine.

25
00:01:33.860 --> 00:01:35.800
So cut from here to there.

26
00:01:36.240 --> 00:01:40.974
But before I press and I confirm this, I actually want to

27
00:01:40.975 --> 00:01:43.720
press C and that's going to cut it all the way through.

28
00:01:44.000 --> 00:01:48.580
Otherwise, I'm just going to be cutting the faces that are facing me right now.

29
00:01:48.581 --> 00:01:54.080
So I already press C and I'm going to click here and enter to confirm.

30
00:01:54.500 --> 00:01:59.220
And it has indeed cut all the way through, cut all the way through.

31
00:01:59.580 --> 00:02:04.820
So I'm going to choose these guys here and I'm just going to delete them.

32
00:02:04.880 --> 00:02:05.880
Boom.

33
00:02:06.280 --> 00:02:12.140
And so this is fixed, except there's a gaping hole here.

34
00:02:12.540 --> 00:02:14.080
And it's an easy thing to fix.

35
00:02:14.120 --> 00:02:18.022
You can pick these two vertices and press F and it'll like

36
00:02:18.023 --> 00:02:21.180
make a face in this direction to kind of close it off.

37
00:02:21.220 --> 00:02:24.660
You can just continue pressing F and it goes all the way there.

38
00:02:25.260 --> 00:02:28.480
And just to be sure, I can do the merge by distance again.

39
00:02:28.540 --> 00:02:31.240
It has no zero vertices removed.

40
00:02:31.241 --> 00:02:32.961
That's just because it's already watertight.

41
00:02:33.140 --> 00:02:37.700
So now this is completely watertight, as far as I know.

42
00:02:37.980 --> 00:02:40.780
Maybe I'll find out later that I made a mistake.

43
00:02:40.980 --> 00:02:41.980
We'll see.

44
00:02:42.540 --> 00:02:45.540
So what I can do now, I can...

45
00:02:46.820 --> 00:02:50.820
Well, I could, for example, you know, to have the text also here at the bottom.

46
00:02:51.980 --> 00:02:53.816
You know, there's a couple of ways of doing this right now.

47
00:02:53.840 --> 00:02:58.500
Maybe I'll, you know, I can like just copy everything here inside of the object and

48
00:02:58.501 --> 00:03:00.760
rotate around, or I can just do two objects.

49
00:03:01.980 --> 00:03:05.120
You know, for now, let's do two objects just to test it out.

50
00:03:05.280 --> 00:03:07.040
Maybe that's too much for the boolean.

51
00:03:07.560 --> 00:03:10.000
Maybe the calculations are already getting a bit shaky.

52
00:03:10.001 --> 00:03:12.740
But I like working as non-destructive as possible.

53
00:03:13.000 --> 00:03:14.960
So I'm just making actually an instance of it.

54
00:03:14.961 --> 00:03:18.380
So it's Alt D and I rotated 180 degrees.

55
00:03:19.000 --> 00:03:20.160
So this is looking good.

56
00:03:21.180 --> 00:03:29.060
And now I'm going to add a boolean for this text that has become a mesh.

57
00:03:29.280 --> 00:03:32.879
By the way, if you try to do boolean and you try to pick a

58
00:03:32.880 --> 00:03:35.840
text that is just a text object, you just cannot pick it.

59
00:03:36.100 --> 00:03:37.320
It has to be a mesh.

60
00:03:37.680 --> 00:03:39.980
So that's why you have to convert it into a mesh here.

61
00:03:40.000 --> 00:03:41.700
So I'm going to pick it now.

62
00:03:42.040 --> 00:03:43.500
Okay, that looks successful.

63
00:03:43.501 --> 00:03:45.600
So I'm just going to go into local view to see it.

64
00:03:45.601 --> 00:03:46.840
Yes, successful.

65
00:03:47.220 --> 00:03:51.660
Going back and I'm going to do another one for the bottom text.

66
00:03:52.500 --> 00:03:56.280
So boolean, union and pick.

67
00:03:56.900 --> 00:03:57.380
All right.

68
00:03:57.381 --> 00:03:59.080
And again, local view.

69
00:03:59.340 --> 00:04:00.140
Yes, perfect.

70
00:04:00.280 --> 00:04:02.380
Okay, so this worked great.

71
00:04:02.420 --> 00:04:07.300
And you know, now I can choose these two meshes, the text meshes.

72
00:04:07.301 --> 00:04:10.220
And I can put them to add.

73
00:04:11.540 --> 00:04:13.196
And so they're not going to be in the way.

74
00:04:13.220 --> 00:04:14.400
And that's it.

75
00:04:14.460 --> 00:04:16.900
Now we have our coin and it's ready to go.

76
00:04:17.220 --> 00:04:22.640
So all you have to do now, you select just this one coin and you go export,

77
00:04:22.820 --> 00:04:25.460
file export and STL.

78
00:04:25.960 --> 00:04:35.620
So what I have noticed with a lot of the people online talking about how to use

79
00:04:35.621 --> 00:04:40.380
Blender for 3D printing and whatnot, they seem to be very destructive in how

80
00:04:40.381 --> 00:04:45.960
they prepare everything to be exported into STL.

81
00:04:46.800 --> 00:04:51.060
And it seems like they are unaware of this little check mark here.

82
00:04:51.380 --> 00:04:54.736
So they keep saying, and I know this is one of

83
00:04:54.737 --> 00:04:57.620
the inspirations why I wanted to do this video.

84
00:04:58.080 --> 00:05:04.020
They keep making you apply these modifiers, which is a very destructive process.

85
00:05:04.021 --> 00:05:08.194
But you technically don't have to do it because there

86
00:05:08.195 --> 00:05:11.920
is an apply modifier option in the export itself.

87
00:05:12.320 --> 00:05:15.797
So make sure you have selection only because

88
00:05:15.798 --> 00:05:18.560
you just want to do the one selected piece.

89
00:05:18.561 --> 00:05:21.800
You don't want all the extra stuff from the file itself.

90
00:05:22.240 --> 00:05:23.240
So selection only.

91
00:05:23.940 --> 00:05:26.560
And then have the apply modifiers be check marked.

92
00:05:26.980 --> 00:05:29.280
And then you can, yeah, it's called coin already.

93
00:05:29.760 --> 00:05:30.760
Export.

94
00:05:31.000 --> 00:05:31.960
And that's it.

95
00:05:31.961 --> 00:05:33.820
You got your coin right on.

96
00:05:34.260 --> 00:05:36.100
So this is what it looks like in the slicer.

97
00:05:36.180 --> 00:05:40.720
You can go through the different layers to see if they're all working or not.

98
00:05:41.060 --> 00:05:44.760
The printing itself went really well and there were no surprises.

99
00:05:45.320 --> 00:05:47.820
It's always exciting to see the thing in real life.

100
00:05:48.160 --> 00:05:52.280
And now that I can have it in my hand and I can touch it and feel it and see how the

101
00:05:52.281 --> 00:05:56.540
light hits it, I do have some ideas of how to improve the design.

102
00:05:56.880 --> 00:06:00.660
But for now, I am very happy and I think this was a success.

103
00:06:01.040 --> 00:06:03.840
Thank you so much for watching, guys, and I hope you learned something.

104
00:06:04.460 --> 00:06:05.460
Bye!
